2005 Sienna- firing order/ #1 cylinder location
I have a 2005 sienna XLE V-6 3.3 L, check engine light, SCV light and TRAC light all on at same time. scan says P0051 HO2S Heater Control Circuit Low ( Bank 2, Sensor 1 ). I gather that is one of the oxygen sensors before the converter. My question is what side of engine is cylinder number one on, is bank 2 opposite side on number one cylinder or same side, would that be closest to front of van or closest to fire wall ? I seem to get conflicting info when I try to research it. I don't want to buy the wrong sensor as I see there not cheap. any pics would be great also. thanks...
